Contact
Email is the only channel. There is no contact form on this site, because a form posts data to a server and this site has a form-action 'none' header specifically to make that impossible.
What is most useful to hear about
- A document that parses elsewhere but fails here, or the reverse. That is a parser bug and it is the most important kind. Include the smallest input that reproduces it.
- A wrong or outdated error message on one of the explainer pages. Runtimes change their wording; V8 rewrote nearly all of its JSON messages in 2022. Tell us your runtime and version.
- A claim on this site you believe is false. The site's argument is that it is careful, so an error here costs more than it would elsewhere. Corrections get published on the changelog.
- A conversion that loses data without saying it did. Every converter is supposed to report the decisions it made. One that fails to is a bug.
- An accessibility problem. Keyboard traps, contrast, screen reader behaviour.
Please do not send us your payload
If a bug involves data you cannot share, reduce it to the smallest input that still reproduces the problem, with the real values replaced. We would rather have a five-line reproduction than a production response, and the entire point of this site is that we never see the latter.
Feature requests
Worth sending, with one standing exception. Anything that would require sending your document to a server cannot be built here: no saved links, no shareable URLs that store data on a server, no load-from-URL, no accounts. Those are not missing features, they are the trade that makes the privacy claim mean something.
